Scientists have been drilling ice sheets and analyzing the ice cores since the 1950s, particularly in Antarctica and Greenland. Areas with accumulating snow turn to ice with air bubbles that preserve samples of the atmosphere from world atmospheres of the past. Scientists are able to analyze the cores to learn about past changes in the concentration of atmospheric gases and the glacial

The European Project for Ice Coring in Antarctica (EPICA) is a multinational European project for deep ice core drilling in Antarctica. Its main objective is to obtain full documentation of the climatic and atmospheric record archived in Antarctic ice by drilling and analyzing two ice cores and comparing these with their Greenland counterparts ( GRIP and GISP ).

Ice Core Drilling Symposium, August 1974 JOHN F. SPLETTSTOESSER Ross Ice Shelf Project Management Office The University of Nebraska, Lincoln Lincoln, Nebraska 68508 It has long been recognized that glacial ice cores, which contain a preserved atmospheric record, must be retrieved and studied in order to evaluate Earths climatic and related parameters. Drilling is the only way of retrieving ice

project ”The Greenland Ice Sheet – Stability, History and Evolution” which was invited to be one of the lead proposals for IPY. The size of the logistic, technological and scientific effort required has led to a realisation that ice coring efforts must be multi-institute, and often multinational, from the three-nation Dye-3 drilling to the 10-nation efforts of EPICA. We propose to build

It was data obtained in these early drilling projects that ultimately led to the discovery of rapid climate changes and served as the foundation and justification for the follow-up in
Deep ice core drilling at Vostok station began in 1970. In the 1970s a set of open uncased holes were drilled by a thermal drill system suspended on cable. The deepest dry hole in ice reached 952.4 m (Hole #1, May 1972). It was con-cluded that for drilling at greater depths it is necessary to prevent hole closure by filling of the borehole with a fluid. Thus, from 1980 on new thermal and

In ice core drilling, when an annulus has been drilled around the core to be retrieved, the core is still attached to the ice sheet at its lower end, and this connection has to be broken before the core can be retrieved. One option is to use a collet, which is a tapered ring inside the cutting head. When the drill is pulled up, the collet compresses the core and holds it, with loose ice chips

Drilling of the warm ice is extremely difficult with electromechanical drills because as the drill penetrates into warm ice, refrozen ice begins to build up on the cutters and shoes of the drill head, and the performance of the drill rapidly deteriorates to a point where penetration stops.
